Exercise 3 For an RL circuit, the equations of the voltage and current is given as under v(t) 20 cos(2500) f(t) = 10 cos(2501 +60) Plot the relationship between 0 and it where time is between 0 to 100 milliseconds with an interval of millisecond. Also, plott), ict) and impedance of this Recircuit with respect to time. Hint: Make sure to convert the angle (given in degrees) in radians before computing) -- Exerched: The voltage V(!) (in) and the current (CE) in Amp) t seconds after closing the switch in the circuit shown are given by Vcc) = V(1 – t) V. ict) R where T, = RC is the time constant. Consider the case where Vo = 24V, R = 38001 - 4000 x 10-'F. Write a program to determine the voltage and the current during the first 20 seconds after the switch is closed. Create an array with values of times from 0 to 20 seconds with spacing of 2 seconds and use it for calculating V(t) and ke(t). Display the results in a three-column table where the values of time, voltage and current are displayed in the first second, and third columns, respectively (0) ww R V.
